AIR BEGISTER.

Application filed June 7,

This invention relates to an air register, primarily intended for use in a heating or ventilating system for buildings, and preferably setin' the Wall of the room, near the floor. v n The general Object of the invention is to provide a register in ,which the shutters, when Open, will' have the same appearance as a fiXed bar design Or 'grating, permitting the free passageof a maximum current of hot air tl ierethrough, and will, when closed, present an attractive panel efi'ect with a polished surface, which may easily be kept clean and sanitary. In the preferred form of the invention, the frame containing the shutters i's removaly secured in an Outside.

frame, which is secured at the outl'et of the stack or flue, between abutting ends -of the base board. I

The specific construction of the invention and the advantages resulting therefrom will be more particularly described in connection with the accompanying drawing, which il lustrates the same in its preferred form.

In the drawin Figure 1 is a ont elevation of the invention, the view being broken and the upper part closed, while the lower part is open,

Figure 2 is a Vertical section through the register as shown in Figure '1,

Figure 3 is a horizontal 'section looking' downwardly with the register closed.

igure ,4 is a horizontal section looking 'upwardly with the register open.

showing a portion of one of the shutters and the means for cp'ntrolh'ng the same.-

In the form shown in the drawing, the register comprises an outer rectangular' frame-lO, made from strips of metal, channel-shaped'in cross section, and secur-ed together at the corners by Welding, or Other suitable means. The inner portion of the frama 10 is bent inwardly, as at'll, to form a seat for receivin'gthe innenfrarne 12. Luge 13 are pressed out of the lower rail of the outer' frame 10, and the lower edge of the 'france 12 s held by therlugs 13 against the .seat 11, while the upper edge of the frame 12 is secu'red to its 'seat by screws 14. ,The inner portion of the frame 12 is turned inwardly to form peripheral flanges r 15, within which the shutters 16 are located. One edge of each Shutter is rolled about a 65 rod 17, which is secured to flanges 15 at the Figure 5 is a detail erspective view, D

register is closed. One end of each lip 18' is cut and bent into a horizontal plane to form an ear 19, which is pivoted on a pin 20,

integrally Welded, or otherwise secured, to

a horizontal bar 21. The ends ofvsome or all 'of the pins 20 are upset'sufiiciently to preve'nt the bar 21 from becoming separated from the shutters. The edges 22, from which the ears 19 are cut form shoulders which are engageable by the bar 21 to limit the opening movement of the shutters.- A

finger 23, secured to one of the shutters,-

affords a convenient means for opening and closing the register. j

When the register is open, it will be noted that all of the shutters are in planes perpendicular to the face of the register, and the rolled edges thereof have the same appear-' ance as the ordinary fixed bar design or grating, beneath which a valve or Shutter is placd. The present construction, however, has the advanta'ge that when the shutters are closed,they constitute, in effect, .a series of panels. The surface of these panels, as well r as the surface of the frames surrounding them, is highly polished, so that it not only presents an attractive appearance but afford's no place for dust to collect, so that it may easily be kept clean and sanitary.

While I have shown and described the preferred form, it is, of course, to be understood that the shape, relative dimensions and relative size may, be .considefiably modi- V fied without any material departure from the 'respective rods, each Shutter having One edge rolled about its rod to form a hinge connection therewith, and the Other edge ofl'- set'to fit beneath the rolled edge of the next Shutter so astopresent a panel effect when the shutters are closed and presentthe appearance of 'a fixed bar designwhen the shutters are Open, one rear corner portion of each Shutter being slit longitudinally and bent at right angles to form' a projecting ear, a bar having series of projecting fpins on Which the ears are pivoted, the edges rom Which the ears are cut forming shoulders engageable by said bar to limit the opening movement of .the shutters.

2. In an air register, the combination of an *outer rectangular frame having the inner 'portion Ofits face depressed to form a seat,

'an inner rectangular frame having a peripheral flange adapted to rest on said seat, means cooperating with said flange for removably securing it On the seat, equi-distant rods secured to the inner frame and extending across .the Opening therein, aseries of to form a hinge connection, and the Otheredge Ofi'set to fit beneath the rolled edge of the next Shutter -so 'as to present a panel effeet When the shutters are closed and to present the appearance of a fixed bar design When the shutters are Open, an ear formed at one corner of each Shutter, a bar connecting the ears and pivoted thereto, and shoulders formed on the respective shutters and engageable by the bar to limit the opening movement of the shutters.

In testimony that I claim the foregoing as my OWn, I have herto afli xed my signature.
